20 Claims.

Our invention relates more particularly to that type of card punches in which the punch actuators are placed in position by a board of selective keys such as is described inthe patent issued to Welk, No. 1,981,932, which relates to a punch to notch the cards described in the patent to Perkins, No. 1,544,172.

As described in the Welk patent, a card is illustrated having a single row of holes punched adjacent the margins of the card. These holes are divided into series of groups of four holes representing either singly or in combination the numerals 1 to '10.

As shown in the Perkins patent, referred to, the card is illustrated with a double row of holes. These holes are also sub-divided into groups and a fourth hole is added to each group which rep-' resents the numerals 1 to 10, the fourth hole being located under and in oifset relation to the other three holes. This arrangement permits a i more extended codification on a card of given size as it permits the arrangement of more groups of holes which practice has shown is very desirable.

As described in the Welk patent, the punch is used to notch certain holes from the hole to the .edge of the card to facilitate the sorting of the cards with a needle, while in the Perkins patent the card is shown to be notched from either row of holes to the edge or margin of the card, but in both of these cards there is no provision for the numeral 0 other than by omitting to notch the card. Due to this arrangement it becomes necessary, in order to segregate the 0 cards to sort out all the other numerals first. Where a double row of holes is employed as shown in the Perkins patent, it becomes necessary under certain conditions for the notch to extend from the edge or margin of the card down to the hole on the inner row. To obtain this result would require either two machines like the Welk patent-one for the outer row and one for the inner row or else a complete change of punches, the expense of which would be excessive.

Our invention has for its principal object to provide mechanism for punching cards having a double row of holes adjacent their edges. The holes in the inner row being in line with the holes in the outer row instead of being staggered as shown in the Perkins patent.

A further object is to provide for positioning the card by means of the holes rather than by trance of .a card positioning plunger which is arranged to enter the positioning hole just prior to the portion of the punch for notching the card.

A further object of the invention is to arrange the key buttons in straight rows, instead of staggered as shown in the Welk patent, so as to conform to adding machine practice and operation, since as operators become familiar with such key board it facilitates the operation of the key punch.

A further object is to provide for a sectional punch for notching either the outer or inner row of holesone or both of the sections being actuated as desired by the same punch actuating mechanism.

' Our means of accomplishing the foregoing objects may be more readily comprehended by having reference to the accompanying drawings which are hereunto annexed and are a part of this specification, in which v Fig. 1 is a plan View of our improved punch, part of the casing being broken away so as to disclose the interior construction;

Fig. 2 is a side elevation of the device shown in Fig. 1 taken on the line 22 in Fig. 1;

Fig. 3 is an enlarged fragmentary detail view showing the punch actuating mechanism shifted to a position for actuating the lower section of the sectional punch for notching the card;

Fig. 4 is a similar view where the punch actuating mechanism has been lifted sufliciently so that it will engage both sections of the punch;

Fig. 5 is a fragmentary detail view partially in section showing the punch actuating mechanism in position to actuate the card positioning plunger just prior to the actuating of the key notching section of the punch;

Fig. 6 is a perspective detail view of the card positioning plunger;

Fig. 7 is a perspective detail view of the other in section, showing the repeat mechanism in its normal position; and

Fig. 13 is a similar view of Fig. 12 but'with the repeat mechanism shown in its operating position.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, the mechanism is contained in a casing l and comprises a plurality of keys 2 which are arranged to actuate a lever such as is described in the Welk patent referred to. Each of the keys 2 is secured in suitable manner to a key stem lever 3. These levers are arranged in pairs and mounted to rock upon a shaft 4 which extends from one end wall of the casing to the other end wall (not shown). The inner ends 5 of each pair of key stem levers are in the same plane as a rocker arm or punch actuator I which serves to reciprocate the sectional punches which will be more specifically described hereinafter.

The rocker arms I swing on a rocker arm shaft 8, a slot 9 being provided adjacent the upper end of the rocker arm I through which the shaft passes. This slot permits the vertical reciprocation of the rocker arm I, in order to bring the shoulder 1' in position to abut a punch to press it inwardly and cause it to notch the card.

Inasmuch as these rocker arms I and their actuating mechanism are fully described in the Welk patent above referred to, a specific description is not deemed necessary.

A slot I0 is provided in the top portion of the casing for the reception of the cards one of which is clearly shown in Fig. 11. A suitable die I2 is mounted below the slot 1.. The sectional punches are slidably mounted in the die |2.

These punches, as more clearly seen in the detail views in Figs. 6, 7, 8, and 9, are made in sections. Figs. 6 and -7 show one pair of sections, the upper section |3 forms a card positioning plunger M. This section I3 is provided with a head |5 which is fitted to a slot l6 formed in one end of the lower section II. It will be clearly seen'from the drawings, particularly Fig. 2, that since the head I5 projects below the lower surface of the section 1, ai'fsufiicient distance to engage the shoulder I on the rocker arm I, that the upper section 3 will be moved before the rocker arm I abuts the notching section or moves it at all.

The result of this construction is that the swinging of the rocker arms I as shown in Fig. 5, will contact the head l5 of each of the sections 3, causing the card positioning plungers M to enter the holes l8 formed in the card II as clearly seen in Fig. 5. This operation will be in advance of any movement of the lower section H which is to notch the card by the further movement of the rocker arm 'I on the shaft 8.

-This further movement of the rocker arm I will move both the lower and upper sections and the punch will be pressed through the card forming a notch as indicated at |9 in Fig.'11.

It will be clear from the foregoing that any swinging movement of the rocker arms I will always cause the positioning plungers M to enter the holes |8 formed for that purpose and thus the card will not only be positioned by these plungers before the notching can take place but will be held in exact location during such operation.

When it is desired to notch the card so as to cut out the portion between the edge and a hole in the inner row, a sectional punch such as shown in Figs. 8 and 9 is employed. As shown 'in Figs. 8 and 9 this punch consists of an upper section-20 adapted to notch the cards as indicated at 9 in Fig. 11. This section 20 is mounted and slides in a slot 2| formed in the lower section 22 of. this punch. This lower section being used to notch the card in combination with the section 20 as shown at 23 in Fig. 11.

It will be apparent that, as in the case of the sectional punch shown in Figs. 6 and 7, the same rocker arm or actuating mechanism is employed to operate either the section 20 alone or the sections 20 and 22 at the same time. In order to prevent the sections moving with each other due to the frictional engagement of their surfaces we provide,'as clearly seen in Figs. 3 and 4, a

' out undue frictional resistance.

The lower section 22 of this punch is preferably provided with a pin 21 which slides in a slot 28, formed in the support 29 for the die block |2. vThis pin serves to limit the longitudinal movement of section 22.

A somewhat similar construction is provided for the lower section H of the other sectional punch. A detent 30 engaging a slot 3| formed in the bottom of the section II. A coil spring 32 is provided to hold the detent normally projected as clearly shown in Fig. 5.

Having selected the desired punch and depressed its key thus elevating the rocker arm into position to abut the desired punch, the operator presses upon the hand lever 50 (if it is manually and not electrically operated) this swings a crank shaft 5| and moves the crank arm 52. The arm 52 is pivotally connected to a link 53 which is pivoted adjacent the lower end 54 of the rocker arm I. The rotation. of

. shaft 5| operates to swing the rocker arm I on the shaft 8. A coil spring 55 is provided to return the parts to their normal position.

The means employed to hold the key .stem levers 3 in elevated position is somewhat similar to the one employed in our copending application, Serial No. 40,580, in which a vertically movable plunger 33 engages notches 34 and 35 formed in the upwardly projecting portion 36 of the key stem lever 3. In the copending' application these plungers are held down by coil springs. Practice has shown that in arranging these detent plungers close together it was impractical to secure a coil spring which would provide sufiicient resistance, as their close spacing necessitated a spring of extremely small diameter. In the present instance they are held down by the means of fingers of a flat spring 37 which may be secured to the upper portion 38 of the guide 39 for the key stem levers. The spring is shaped so that each finger will press upon a plunger.

Each one of the pair of key stem levers 3, as shown in Fig. 3 which is to actuate the lower section of the punches is provided, with a stop 40 Which engages the wall of the guide 39, this prevents the key stem lever from raising the rocker arm I more than the distance which will be required to bring it in position to operate the lower section of the punch. The other key stem levers 3', as shown in Fig. 4 which are designed to be employed where both sections ofthe punch are to be actuated are not provided with the stops 40, consequently when operated the rocker arm I will be lifted sufiiciently to engage the end face of both sections of the punch or until the bottom of the slot 9 engages the shaft 8.

The notches 34 and 35 on the key stem levers, employed for this purpose, are more widely separated than are the notches 4| and 42 011 the levers having the stop 40 formed on them, in

order to provide for this additional movement.

The forward portions of the key stem levers are secured to the key stems in the usual manner with the exception of those bearing numerals 0 or 1. These are pivoted to a compensating lever 43 to which is pivoted the key stems. This lever swings on shaft 44. In this manner we avoid the excess movement which would otherwise result from the depression of the keys bearing numeralsO or 1.

We have provided an improved arrangement for the restoring key 45. Practice has shown that it is better if possible to avoid the hinged parts shown in our copending application above referred to and greater efiiciency is attained by having the key stems 46 of the restoring keys 45.

secured to a cross head 41 which extends across three of the rocker arms. This cross head is prevented from turning by an angle piece 48 which is attached to a rocker arm supporting bar 49.

We have provided a simplified repeat mechanism which comprises a repeat key 56 and its connecting parts. The key 56 projects through the front wall of the casing l. Its inner end is connected to one end 21 of a rocker lever 58 which is mounted on a stud 59. The lower end 60 of the lever 58 is connected to a link 6| which slides on" the crank shaft 5| being guided by the bottom of the die support 29. This link terminates in a head 62. In the crank shaft 5| near one'end is mounted a cap screw 63 which is screwed into the crank shaft 5|. A locknut 64 is provided to hold it in place. As shown in Fig. 12 the repeat mechanism is in normal position and the crank shaft can be freely rotated when however the key 56 is pushed in, as seen in Fig. 13, the head 62 will be moved into the position where the end of the cap screw 63 will contact the head 62 and further movement of the crank shaft is prevented. In this manner the punching operation may be repeated as often as desired.

From the foregoing it will be seen that in normal operation the repeat button 56 is pulled out to the position shown in Fig. 12. This imparts motion to the rocker lever 58 causing it to move link 6| rearwardly sufliciently for the surface 62', on the head 62 of link 6|. When the arm 52 has moved a suflicient amount for the punches to cut through a card as shown in Fig. 13 the upper edge of link 6| will contact with the bottom of a slot in 5| at a fulcrum point 5| and further movement of the operating lever 50 imparts a rapid downward movement to link 53, also rocker arm I.

When the repeat button 56 is depressed as shown in Fig. 13 this downward motion is prevented by contact of screw 63 with surface 62' of head 62 thus providing for notching the cards without restoring the punching mechanism or any of the depressed keys.
